The setting range of the bit addresses to control whether to execute or to stop the com-
munication scan is the internal device address’ LS9550 to LS9557. Each device/ PLC
address starting from Bit 0 is assigned sequentially to each driver’s device/PLC starting
from the first unit.
e.g.)
You can set the bit addresses controlling the communication scan of the Driver 1’s first
to 16th units to LS9550.
[LS9550]
Bit 0: Scans ON/OFF the Driver 1’s first PLC.
Stops the scan (scans OFF) of the Driver 1’s first PLC by turning ON Bit 0. Turn OFF
Bit 0 to resume the scan.

• When you turn OFF the communication scan, the displayed part’s data will remain.
However, if you change screens and then display the screen again, the part’s data will
not be displayed.
